Sorry, that was temporary problem at the keyboard... :)

Ok, now about parameters. You can specify TPB mapping in the connection
string:

TRANSACTION_READ_COMMITTED=isc_tpb_consistency,isc_tpb_write,isc_tpb_wait

There is no chance to tell driver to use other isolation than read
committed, but you can redefine the mapping.
